You don't need a separate meter as such if you have a charging point

government power to require all charging points to have "smart
functionality".Â* They propose to do so for all new home charging points
by 2025.

At the moment, pretty well all electric cars communicate with the
charger* using just some pulses and a diode, but there is the option to
use a full homeplug (data over mains wiring) type connection and there's
a zigbee energy profile for wireless communication between smartmeter
and car.


[*] not really the charger, but it's what everyone calls the thing on
the wall.
